Huawei HiFloat4 Outperforms MXFP4 On Ascend Chips
Huawei's HiFloat4 training format outperformed Western-developed MXFP4 in recent Ascend chip benchmarks. This development suggests that US export controls are accelerating China's pursuit of independent numerical formats. The shift reduces reliance on international standards. Practitioners should monitor how these custom formats affect cross-platform model portability and hardware efficiency.
